**Assembling the 3.5 Inch Touchscreen Display for Raspberry Pi**

The process of assembling the 3.5 inch touchscreen display for Raspberry Pi is relatively straightforward, but it requires some care and attention to detail. The first step is to attach the bottom portion of the case, which comes with a pre-mounted fan. This fan helps keep the Raspberry Pi cool by automatically turning on and off when the CPU gets too hot or too cold.

Next, we need to add the heat sinks for the CPU, RAM chip, and USB controller. The display comes with three aluminum heat sinks that fit perfectly into their respective slots. Mounting these heat sinks is easy and requires only a few screws. It's essential to ensure they are securely attached to prevent overheating issues.

With the heat sinks in place, we can now attach the top section of the case, which provides additional protection for the Raspberry Pi. The case comes with four little brass standoffs that hold everything together neatly. Once this is done, we plug in the fan to the back of the screen and connect it to the GPIO connection on the Raspberry Pi.

Now that our display is assembled, we can proceed to install the driver. We start by cloning the driver from the Raspberry Pi's GitHub repository, which downloads a script needed to install the driver. The script only takes a few seconds to download, making the process quick and efficient. Next, we navigate to the new driver directory, run the auto-install script, and reboot the Raspberry Pi.

After rebooting, the Raspberry Pi should be able to recognize the touchscreen display and its drivers. We can now access the raspbian operating system and test the touchscreen's functionality. The touch sensitivity is great, and the on-screen keyboard works well with the stylus or finger input. However, navigating larger systems like web browsing with a small screen can be challenging due to the tiny on-screen keyboard.

**Using RetroPie for Retro Gaming**

With the 3.5 inch display installed, we can now proceed to set up RetroPie, a popular retro gaming platform for Raspberry Pi. We start by installing RetroPie using the official instructions provided with the kit or through the raspbian operating system. The installation process is relatively straightforward and only requires a few commands.

Once RetroPie is installed, we can configure it according to our preferences. This includes setting up the controller, configuring the display settings, and selecting the games we want to play. In this case, we're using the Sega Genesis controller and Retropie's built-in emulator.

We also test the display's functionality by running a few RetroPie games. The 3.5 inch display works seamlessly with RetroPie, providing clear visuals at 60fps without any screen tearing issues. However, it's essential to note that there is no sound built into this setup, which might be a drawback for some users.

**Power Consumption and Limitations**

While the 3.5 inch touchscreen display adds a new dimension to our Raspberry Pi project, it also increases power consumption slightly. This may not be an issue for most users who plan to use their Raspberry Pi as a media center or for other tasks that don't require constant access to the display.

However, if you're looking to use your Raspberry Pi as a headless server, a smaller screen like this might not be the best choice due to its limited size. In such cases, having a larger screen or a more powerful display would provide better usability and functionality.

In conclusion, assembling the 3.5 inch touchscreen display for Raspberry Pi is relatively easy, but it does add bulk to the device. While it's perfect for projects like retro gaming, smaller screens might be more suitable for other tasks that require more extensive system access. Nevertheless, this project has been a great learning experience, and I'm excited to share my findings with you.

"WEBVTTKind: captionsLanguage: enwhat's going on guys ZTA Prime back here again today we're gonna be taking a look at the i uniquor 3.5 inch touchscreen 60 FPS display for the Raspberry Pi for now unfortunately this does not use HDMI like the older ones for the Raspberry Pi 2 3 and 3 B+ and those screens are not compatible with the new Raspberry Pi 4 because we have micro HDMI on this thing hopefully down the road somebody will release an IPS HDMI display for the PI 4 but for now we'll have to use the GPIO and I have seen this in action it is running at 60fps I haven't seen any screen tearing at all and it looks pretty good now this kit does include a stacking acrylic case heat sinks for the CPU RAM and USB controller plus we get a fan and one of the cool things about this fan setup is it's not constantly on when the CPU hits a certain temperature the fan will turn on and then shut off as soon as it's cool enough this kit is available on Amazon for $32.99 just keep in mind it does not include a Raspberry Pi 4 but it will work with the one gig to Gig and a 4 gigabyte version of the PI 4 and yes you will need to run a script to get this up and running but it's super easy so in this video I'm going to be using this in raspbian we're also going to test it with retropie I'll do a quick assembly we'll do the driver install and then we'll see how this thing performs the kit comes with everything you'll need to get up and running you'll get the acrylic case and this does have a film on it I just don't like pulling it off because this acrylic scratches up really easily but this is what's known as a stacking case and they do have full instructions over on the website in case you get lost so I personally don't really like touchscreens with the Raspberry Pi with any Raspberry Pi operating system really and using a small touchscreen like this with raspbian can be a pain where these screens really shine in my opinion is retro gaming and we will get into that so I have the bottom portion of the case on now it's time to add the heat sinks like I mentioned it comes with three aluminum heat sinks one for the CPU one for the RAM chip and one for the USB controller before I put the top section of the case on we need to mount the fan on the bottom of the screen itself there is a connector for the fan and this is set up to automatically turn on and shut off when the CPU gets hot enough or cool enough so it's not running continuously mounting the fan is easy it comes with the screws and I'm going to put the screws with a Philips head side up so we have the nut on the bottom once the fan is mounted to the top plate we're gonna secure the top section of the case on to the rest of the Raspberry Pi four there's four little brass standoffs to hold everything together now it's time to plug in the fan to the back of the screen and plug the screen into the gpio connection on the Raspberry Pi 4 so it's all mounted up I mean it's a really simple setup process but we still have that driver to install so we're gonna go over that real quick alright so let's go ahead and install the driver now I have installed raspbian this is the latest version is fully up to date when you get your kit you'll get a little tag that shows you exactly which website you need to go to and there are full instructions here but I'm gonna go over them real quick the next thing we need to do is clone the driver to the Raspberry Pi from their github this is going to download the script that we need to install to get this up and running it only takes a few seconds so now that we have that clone we need to CD into that new driver directory we're going to point our terminal to that directory and now we just need to run the auto install dot s H that was downloaded with the packages and that's it everything's installed we just need to do a reboot you can type in sudo reboot and when the Raspberry Pi reboots your 3.5 inch touchscreen will be functional so we now have the unit assembled we have the driver installed as you can see it definitely adds some bulk to the Raspberry Pi 4 but I expected it because we're adding a screen to the top of the pie let's go ahead and move over to the raspbian operating system and see how this thing functions and then we'll get into a little bit of retro gaming so here it is the touch screen sensitivity is great you can calibrate it from within the raspbian operating system you do have an on-screen keyboard with this driver installed and the stylus works or you can use your finger for touch the screen can also be rotated by editing the config dot txt file but like I said this operating system really isn't meant for a screen this small navigating the system with touch is easy enough but when it comes to like web browsing and things like that the on-screen keyboard is super small and it's just kind of hard to get around with several screens opened up but the screen is great with other operating systems or specific apps that work better on smaller screens like monitoring systems and if you were interested in running your raspberry PI's let's say a server headless now having a headless server is really awesome you can log in from another device to see what's going on but if you added this screen it's not going to add that much more power consumption and you'll always have that display so you can check the information but for retro gaming a small screen like this works pretty well I would like to add a battery to this setup but right now I have my game Sergi 3s controller with the mount the PI is plugged into the wall but as you can see I'm running retro PI and we'll get into a little bit of testing I haven't noticed any screen tearing and it's definitely running at 60fps but unfortunately there is no sound built into this setup you so as you can see it functions quite well with retropie and I can't wait till the guys over at retropie release an official image so overall the screen does function well I really wouldn't recommend this if you want to run let's say a full-fledged desktop operating system on the Raspberry Pi even a 5-inch screen is a little too small I would at least go with the seven but for certain projects the i uniquor 3.5 inch screen could definitely come in handy so that's pretty much it for this video guys I really appreciate you watching if you're interested in picking one of these up I will leave links in the description if you have any questions at all let me know in the comments below it'd also be really cool if you could hit that like button or maybe
